| titleOfInvention | Exhaust gas purification device for internal combustion engine |
| abstract | An exhaust gas passage for rotating the exhaust gas flow in the circumferential direction around the axis of the exhaust gas flow passage system is formed on the upstream side of the catalyst device in the exhaust system passage to promote mixing of the exhaust gas and urea water. By providing a mixing acceleration chamber that allows exhaust gas and urea water to flow in the circumferential direction, the distance for mixing is secured, the length in the exhaust system direction is made compact, and the overall thickness of the device is reduced Then, it aims at improving the mounting property to the vehicle of the exhaust gas purification device, the mounting property to the vehicle, and the like. A selective reduction catalyst 8 is provided in an exhaust system path of an engine 1 to purify exhaust gas by supplying an additive, and is provided on an upstream side of the selective reduction catalyst 8, and exhaust gas is centered on an axis of the exhaust system path. The exhaust gas flow passage 79 (85) for rotating the exhaust gas flow along the circumferential direction is formed, the mixing promotion chamber 7 (8) for promoting the mixing of the exhaust gas and the additive, and the exhaust gas in the exhaust gas flow passage 79. A urea water injection nozzle 9 for injecting an additive into the exhaust gas flow passage 79 is provided in the vicinity of the introduction hole 76. [Selection] Figure 3 |
